reMarkable 2 not detected at Calibre startup

[robfreundlich]

My reMarkable 2 is connected via USB, and I can successfully ssh to it at IP address 10.11.99.1. I have the plugin configured as follows:

(the password is the correct one)

And yet, when I start Calibre, it doesn't see the device. When I run calibre-debug -g, I see this in the output, but no more details:

Hey @RobFreundlich , thanks for opening the issue. I need to dedicate some time to figure out why this is happening. Are you using the code directly from master? or one of the packaged releases?

[robfreundlich]

Howdy!

That's an excellent question! And, unfortunately, one that I can't answer for certain, because it was more than a week ago :-) But I'm gonna say that I grabbed it from master, because I don't remember and the only references to it that I can find in my browser history are the github page.

Same error here, in Windows using the latest release zip file:

I think this is the actual root of the error: ImportError: cannot import name 'asn1' from 'cryptography.hazmat.bindings._rust' (unknown location)

I suspect the issue is that this import requires native code to be compiled on the target, which Calibre may not handle (I'm actually not sure): https://github.com/pyca/cryptography/issues/4927#issuecomment-503189967

[DakotaNelson]

Ok, I think the import is the root issue.

So the issue is in paramiko, specifically its dependence on asn1, which I think is because it relies on native code. Ignoring the problem importing lets you connect to the device successfully, buuuuut then it fails when it tries to actually go in and do stuff (using paramiko).

Not sure if there's a way to pre-install paramiko/asn1 in a way that calibre's embedded interpreter can pick it up, or... something.

[posita]

Any update on this? Anything those of us encountering this issue can do to help get it fixed? Alternatively, is there a prior working version? (I suspect no, given the nature of the issue.)

[mfouesneau]

Yes please

[xals]

The PR #16 should fix this issue.

[xals]

After further reading of this issue, my PR seems to be not related to the errors you reported, but fixing device space retrieving as I did allowed me to see the device and send documents on it.

I just realized that the behavior has been changed in master so my PR is not relevant unless you want to remove the device storage configuration parameter.

[xals]

Hello, I modified the PR to include the configuration parameter storage. And if you set it to /home/root it works fine, and should be compatible with reMarkable 1 and 2.

[Kenivia]

Hey guys, I've found a workaround for this.

In the __init__.py file, around line 32: sys.path.append(self.plugin_path) What's being added to sys.path is the path to the zip file, as documented here, which can't be opened by python for importing.

Step by step workaround:

1. Download the repository
2. Open __init__.py, go to around line 32 where it says sys.path.append(self.plugin_path)
3. Replace self.plugin_path with the path to where you've put Calibre-Remarkable-Device-Driver-Plugin/ folder, PLUS target at the end(we will make the target folder later) e.g: sys.path.append("/home/kenivia/Desktop/Calibre-Remarkable-Device-Driver-Plugin/target/")
4. Make sure that your active system(or conda) Python version is 3.10(Otherwise the plugin will say that it failed to import _cffi)
5. Run create_plugin_zip.sh, this will create the target folder and a zip file
6. Keep the target/ folder somewhere safe, e.g. desktop, so that it is there whenever you run calibre. Make sure that the path in __init__.py still points to the target folder
7. Install the plugin through Calibre preference normally using the zip file generated previously. If you change __init__.py, make sure you generate the zip file again. Alternatively, run calibre-customize -b ./ from the folder, but you may have to first delete the zip file.

I should mention that this question & answer helped pinning down the problem

[atze007]

How exactly can I create the new ZIP file? Or more precisely, how does step 5 work? When I compress it "normally" I get the following error calibre-remarkable-device-driver-plugin.zip' is invalid. It does not contain a top-level __init__.py file

[Kenivia]

@atze007 The script create_plugin_zip.sh will 1: make a target folder and put the libraries in it and 2: put both the target folder, __init__.py, config.py and the other files into a zip file. It puts the zip file in the same folder as the script. The script will make the zip file for you, you shouldn't do it yourself.

[atze007]

@Kenivia I'm sorry, but I'm at a loss at the moment.... Where can I get the scirpt? 🙈

[Kenivia]

@atze007 It’s in this repository 👍

[atze007]

@Kenivia oh... 🙈 so, sorry....
